Year 6 Students Lead Real-World Sustainability Initiative at The Grange Institution

At The Grange Institution (TGI), learning goes beyond the classroom. Guided to become Resilient Innovators and Reflective Learners, our students apply their knowledge to solve real-world situations that matter.

This was exemplified by our Year 6 students, who transformed a classroom discussion on sustainability into a practical, student-led project.

From Classroom Learning to Real-World Problem Solving

The project began with an important  question: How can we reduce everyday waste within our community?

As students explored environmental issues such as food waste and sustainability, they identified used coffee grounds as a sustainable resource that could be used to enhance soil quality.

TGI student ambassadors from The Alliance for Sustainable Schools (TASS), Leixton Calonzo and Ren Yashiro, led the initiative by:

• Researching the benefits of repurposing used coffee grounds
• Exploring how their findings could be applied at The Grange’s Agroforest Farm
• Identifying a community partner that could supply used coffee grounds

 

They explored different ways to repurpose used coffee grounds, discovering that they could be processed into both solid and liquid fertilisers for use at the Agroforest Farm. These fertilisers help enrich soil and support healthy plant growth.

This reflects The Grange’s approach to education, empowering students to identify problems, engineer solutions, and take meaningful action.

Applying Communication Skills in Authentic Contexts

To bring their idea to life, Leixton and Ren worked with their class teacher to draft a formal email to Starbucks, requesting used coffee grounds. This provided an authentic opportunity to practise professional communication in a real-word context.

After receiving a positive response, they visited the Starbucks outlet at Seletar Mall, where they introduced themselves, thanked the store manager, and engaged in meaningful dialogue about their goals for this initiative.

Through experiences like these, students develop the confidence and communication skills needed to navigate real-world situations.

Developing Critical Thinking Through Reflection

Reflection is a key component of real-world learning.

Students reviewed:

• What worked in their approach
• Challenges they encountered during communication and coordination
• How future efforts could be improved

 

This process strengthened their critical thinking and reinforced that effective problem-solving requires persistence and resilience. By engaging with real stakeholders, students developed a strong sense of agency and responsibility. These are essential qualities  for active citizenship.

Fostering an Entrepreneurial Spirit

Back in the classroom, students explored how waste could be transformed into products with real value. Using the collected coffee grounds, they created body scrubs and natural deodorants, which were later showcased  and sold at the school’s Farm Market.

Through this experience,  students developed an entrepreneurial mindset by learning about product development, usability, and how sustainable solutions can create value while supporting  a meaningful cause.

Continued Student-Led Innovation

The collected coffee grounds will continue to support ongoing initiatives at The Grange’s Agroforest Farm, contributing to a more sustainable campus ecosystem.

This is just the beginning.

Students across the school are already exploring new ways to:

• Reduce waste
• Improve sustainability practices
• Strengthen community partnerships

 

At TGI, we are proud to nurture students who don’t just learn about the world, but develop the confidence, skills and mindset to improve it.
